Abstract
A method and apparatus for removing H.sub.2 S from a process gas, including a reaction chamber between an absorption chamber and an oxidizer chamber, in the polyvalent metal redox catalyzed removal of H.sub.2 S from a process gas. The process and apparatus of the present invention inclues a first gas-liquid mass transfer zone or absorber chamber for intimately containing an H.sub.2 S-containing process gas with an oxidized polyvalent metal redox solution for absorption of the H.sub.2 S; and a reaction chamber in fluid communication with polyvalent metal redox solution exiting the absorption chamber through a valve-controlled cross-flow conduit. Cross flow of solution from the absorber chamber through a valve or other circulation control device to the reaction chamber provides controlled, continuous and sequential gas-liquid contact with two or more different gases in separate absorption, reaction and oxygenation zones within a single or multiple vessels.
